We look at the division of 784891 by 802 
We want to figure out the number of times 784891 can be divided by 802.

Moving on to step 1:
802 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 802

Advancing to step 2:
If we divide 78 by 802, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 802

Advancing to step 3:
If we divide 784 by 802, we get 0 and a remainder of 784.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 784 leaves us with 784.
Append the next digit (8) from the dividend to 784 and continue with: 7848 / 802

On to step 4:
When dividing 7848 by 802, we get 9 with a remainder of 630.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7218 from 7848 and we're left with 630.
Bring next digit (9) of the dividend behind the 630 and repeat the process: 6309 / 802

Let's proceed to step 5:
802 goes into 6309 7 times with a remainder of 695.
The next digit of our result is 7. 
Result so far: 97.0
If we take 5614 away from 6309, we end up with 695.
Include the next digit (1) from the dividend after 695, then repeat: 6951 / 802

Moving on to step 6:
If we divide 6951 by 802, we get 8 and a remainder of 535.
Record the quotient 8 as the next digit in the result. 
Result so far: 978.0
Subtract 6416 from 6951 to get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 7:
The number 802 fits into 5350 6 times, leaving a remainder of 538.
The next digit of our result is 6. 
Result so far: 978.6
Subtract 4812 from 5350 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

On to step 8:
If we divide 5380 by 802, we get 6 and a remainder of 568.
Write down 6 as next digit of the result. 
Result so far: 978.66
Deduct 4812 from 5380 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 978.66 with a remainder of 0.568.
